Tarmet's Arcane Servant

You transform the wooded effigy used in the casting of this spell into a human-sized servant.

The servant is an ally to you and your companions, it rolls its own innitiative during combat, but follows your commands to the best of its ability. If given no commands, the servant defends itself as necessary, but otherwise follows you. You may have no more than two servants at a time.

The servant does not regain hitpoints from taking a short or long rest, but casting the mending cantrip on the servant causes it to regain 25 hit points. The servant may be healed in this way only once each day. 

If the servant is killed, it returns to being a small wooden doll, but is too damaged to function as a component for this spell again. You may spend 1 hour repairing the effigy to make it a suitable component again.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, use the higher level wherever the spell’s level appears in the stat block.
